 What's in a Name? In "German 

 Silver," for Instance 



GERMAN silver is manufactured in 

 r three general ways. It is composed 

 of nickel, copper and zinc in varying pro- 

 portions. The German method is to 

 melt all the copper to be used in the 

 mixture, and two-thirds of the nickel and 

 zinc in a graphite crucible and then add 

 the rest of the nickel and zinc. In the 

 English method the copper, nickel and 

 zinc are melted all at one time, then more 

 copper and zinc are added. Should the 

 metal appear porous, a fireclay pipe con- 

 taining pitch is pushed into the metal mix- 

 ture to deoxidize it. There are several 

 American methods. One is to melt a 

 copper-nickel alloy and then gradually 

 add the preheated zinc. In another 

 method monel metal, is used as a base.

Business is good, thank you, in this the 

 narrowest of stores. Can you see the store? 



You Can Attach This Humidifier to The Narrowest Store. It Is Only 

 Your Radiator Six Feet Wide 



A HUMIDIFIER is now manufactured 

 which may be quickly attached to 

 a flat or round top steam radiator. 

 Two soft pliable wires are passed be- 

 tween the radiator coils to the back of 

 the humidifier, where they are tightly 

 wound round two buttons. This enables 

 the moistening device to be attached as 

 firmly as if it formed part of the radiator. 

 When it is de- 

 sired to remove 

 the water from 

 the humidifier it 

 is only necessary 

 to unloosen the 

 wires from the 

 buttons, then 

 the device can 

 be carried to an- 

 other room for 

 cleaning. When 

 the radiator is 

 not being used 

 during the sum- 

 . mer months, the 

 water in the 

 humidifier may 

 be removed and 

 the box-life part be utilized as a' tem- 

 porary resting place for flowers until 

 they ccin be planted.

ROUND space must be extremely 

 valuable in Corry, Pa., judging from 

 the manner in 

 which the owner 

 of a six-foot strip 

 between the 

 right of way of a 

 railroad and the 

 building line of 

 one of the streets 

 of Corry utilized 

 his property. He 

 erected a brick 

 building, six feet 

 wide and about 

 seventy-five feet 

 long, and in- 

 stalled in the 

 narrow building 

 a lunch room at 

 one end, and a 

 cigar, candy and 

 ice cream 

 counter at the 

 other. The queer 

 structure caused 

 considerable 

 amusement at 

 first, but it proved a good investment. 

 When the railroad encroached about two 

 feet upon the ground, it had to move back. 



The humidifier 

 is made fast to 

 the radiator by 

 two wires pass- 

 ing between the 

 hot-wcter coils
